On-Grid Solar Energy System

On-grid or grid-tied solar systems are by far the most common and widely used in homes and
businesses. These systems do not need batteries, they use either solar or micro-inverters. They
are connected to the public electricity grid. Any excess solar power that you generate is
exported to the electricity grid which results in regular Feed-in-Tariff (FiT) payments or the
equivalent credits.

Off-Grid System:

It is a system which has no connection to the electricity grid hence requires it to have battery
storage. Their design requires precision and sound expertise, so they can work at their optimal
level and generate enough power to meet all your needs throughout the year and have enough
battery capacity to meet the home’s requirements especially during the winters, when there is
less sunlight available.
This system is generally on the expensive side due to the high cost of batteries and off-grid
inverter. Their usage is feasible for remote areas, where the electricity grid is not available

Hybrid System:

Hybrid solar systems generate power in the same way as a common grid-tied solar system but
use special hybrid inverters and batteries to store energy for later use. This ability to store
energy enables most hybrid systems to also operate as a backup power supply during a
blackout, similar to a UPS system.



Households in Pakistan consume overall 44 percent of energy. Our residential systems include both on- grid and battery backup based solar energy solutions. Our battery-based Intelligent Solar Energy System ensures that your solar power is available to you round the clock. Nearly 75% of your annual electricity consumption is covered with self-generated clean energy so less dependency on power generation authorities.


We at Cosmos Energies offer the best possible solutions to all the commercial ventures to fulfill their high energy consumption requirements while avoiding increasing operational costs. Solar installations also highlights an opportunity to make the best investment with a non-shaded roof that serves next to nothing in most cases. With the availability of feed-in tariffs, a business can sell surplus solar electricity to the grid. Your solar installation makes it easy to lower down your operational expenses while enabling you to plan for your future energy requirements.


Heavy peak usage & large available area make solar a perfect energy solution for industries. The high load requirement and largely available rooftop area compared to commercial and domestic consumers make solar a viable alternative for industries. Often, the other incentive for many big industries to use industrial solar power’ is to show an increased share of renewables in their energy portfolio. Solar power in an industry setup can either be generated from an in-house solar plant or through an on-site solar farm. The solar power produced can then be used for all normal day-to-day operations of the plant.
